Description

Technical Field

[0001] The utility model belongs to the technical field of earthquake-resistant brackets, in particular to an earthquake-resistant bracket for laying a cable bridge. Background Art

[0002] The seismic support is used to limit the displacement of the attached electromechanical engineering facilities, control the vibration of the facilities, and transfer the load to various components or devices on the bearing structure. The seismic support should provide reliable protection for the building electromechanical engineering facilities during earthquakes and withstand the earthquake from any horizontal direction; the existing patent (Announcement No.: CN212277816U) is a seismic support for a cable tray. The seismic support of the cable tray is installed with an extrusion block on the limit groove, and a buffer spring fixedly connected to the inner bottom wall of the buffer cavity is installed on the buffer block. When vibration occurs, the bridge body will shake, thereby generating a pulling force on the connecting rod, and the connecting rod will pull the buffer block downward. When the buffer block moves downward, it will be squeezed with the extrusion sheet and the extrusion block. The buffer spring will push the buffer block upward, and most of the inertia will be offset in this process, which can prevent the fixed plate body from falling off, thereby achieving the purpose of good seismic effect; however, the seismic support is very inconvenient to maintain and disassemble, which increases the workload of operators and reduces work efficiency.

[0021] The quick disassembly assembly comprises a worm wheel 9 and a pushing wheel 14. The worm wheel 9 is rotatably mounted on one side of the first mounting plate 7. A worm 10 is meshedly connected to one side of the worm wheel 9. A positioning shaft seat 11 is rotatably mounted on the bottom of the worm 10. The bottom of the positioning shaft seat 11 is fixedly connected to the top of the bridge frame body 5. A hand wheel 12 is fixedly mounted on the top of the worm 10. A first sprocket 13 is fixedly mounted on the side of the worm wheel 9 away from the first mounting plate 7; the pushing wheel 14 is rotatably mounted on the side of the second mounting plate 8 close to the first mounting plate 7. A rotating column 15 is fixedly mounted on the side of the pushing wheel 14 away from the second mounting plate 8.
